Tulip Related Quotes

Most tourists mistranslated Jardins des Tuileries as relating to the thousands of tulips that bloomed here, but Tuileries was actually a literal reference to something far less romantic. This park had once been an enormous, polluted excavation pit from which Parisian contractors mined clay to manufacture the city’s famous red roofing tiles—or tuiles.

As one season’s crop of girls proceeds into engagement and marriage, younger ones keep sprouting up, like tulips in May. They are now so young in relation to Simon that he has trouble conversing with them; it’s like talking to a basketful of kittens.

He suspects she’s flirting with him. It’s far from disagreeable, but, perversely, it makes him think of his mother. How many acceptable young girls has she trailed discreetly before him, like feathered fishing lures? She arranges them, always, next to a vase of white flowers. Their morals have been irreproachable, their manners candid as spring water; their minds have been presented to him as unbaked pieces of dough which it would be his prerogative to mould and form. As one season’s crop of girls proceeds into engagement and marriage, younger ones keep sprouting up, like tulips in May. They are now so young in relation to Simon that he has trouble conversing with them; it’s like talking to a basketful of kittens.

Before 1800 the word “light,” apart from its use as a verb and an adjective, referred just to visible light. But early that year the English astronomer William Herschel observed some warming that could only have been caused by a form of light invisible to the human eye. Already an accomplished observer, Herschel had discovered the planet Uranus in 1781 and was now exploring the relation between sunlight, color, and heat. He began by placing a prism in the path of a sunbeam. Nothing new there. Sir Isaac Newton had done that back in the 1600s, leading him to name the familiar seven colors of the visible spectrum: red, orange, yellow, green, blue, indigo, and violet. (Yes, the colors do indeed spell Roy G. Biv.) But Herschel was inquisitive enough to wonder what the temperature of each color might be. So he placed thermometers in various regions of the rainbow and showed, as he suspected, that different colors registered different temperatures.† Well-conducted experiments require a “control”—a measurement where you expect no effect at all, and which serves as a kind of idiot-check on what you are measuring. For example, if you wonder what effect beer has on a tulip plant, then also nurture a second tulip plant, identical to the first, but give it water instead. If both plants die—if you killed them both—then you can’t blame the alcohol. That’s the value of a control sample. Herschel knew this, and laid a thermometer outside of the spectrum, adjacent to the red, expecting to read no more than room temperature throughout the experiment. But that’s not what happened. The temperature of his control thermometer rose even higher than in the red. Herschel wrote: [I] conclude, that the full red falls still short of the maximum of heat; which perhaps lies even a little beyond visible refraction. In this case, radiant heat will at least partly, if not chiefly, consist, if I may be permitted the expression, of invisible light; that is to say, of rays coming from the sun, that have such a momentum as to be unfit for vision.

4 Meet the astrocyte If you look at a tulip, you wouldn’t think it was an armadillo. Similarly, looking at a neuron, you wouldn’t think it was glia. But you might look at a whale and think it’s a fish, until you look at it closely and realize it has no gills and breathes through lungs. Then, you have a problem. Through genetic testing and excavations by paleontologists, we now know it likely originated as a land animal that took back to the sea and is related to hoofed animals like the horse. But before genetic testing and evolutionary biology, classification was based on appearance. This remains true for cellular classification.
